Hi,

Documentation for Interface says on top +5V_SWITCH, do I need to solder switch or just close this jumper to be able to use the 5V,GND and A1 for example for a joystick? Or is this switch for something else?
Second question is that A1 does it work with 5V joystick or you suggest to stick with 3.3V?
